“…To effectually bridge the gap between the heat wall configurations and its thermal discharge behavior, Vakilzadeh et al utilized a numerical approach incorporating the enthalpy–porosity method to better reflect the melting behavior of the filled RT-27 PCM in the cavity. The curvy nature of the cavity suitably decreased the melting time to around 57.6% and increased the charge storage capacity to around 16.3% compared to the pristine case . Similar works have been reported on the BTMS by employing liquid coolant, fin-based systems, − and the thermal penetration parameters with respective time intervals. − For better analyzing the thermal behavior, neural network structures are also being employed in getting precise results .…”

The emergence of lithium-ion batteries (LIBs) presents a promising solution, yet they come with an inherent challenge of thermal overrun due to rapid charge−discharge cycles. An effective thermal management (TM) strategy is essential to addressing these issues. This study focuses on improving the temperature performance of phase change material (PCM-encased solid-state LIBs (SLIBs) by employing the NTGK module and integrating it into ANSYS Fluent, to assess the discharge behavior of LIBs. Additionally, a comparative analysis of two outperforming LCO/LAGP/G, and LFP/LLZO/Li cell combinations, was examined. The LCO/LAGP/G combination exhibited a 1.8 and 0.68% temperature reduction in capric acid and paraffin wax, whereas the LFP/LLZO/Li configuration showed a 2.7% reduction in capric acid and a 1.45% reduction in paraffin wax respectively.

Advances in non‐conventional energy technologies and increasing fossil fuel prices along with environmental concerns have made hybrid renewable energy systems important. In view of this scenario, solar panel mounted on a vertical axis wind turbine (called as solar‐wind tower) can be utilized to produce more electric energy than individual one. This solar‐wind tower will be located in the space available between two opposite roads of expressways/highways. Solar‐wind tower located in such a manner that the air velocity produced from driving vehicles on both sides of the road is adequate to cut the turbine blades which will produce unidirectional torque. A battery energy storage system (BESS) stores the power produced by the solar‐wind tower so that it can subsequently be used for local loads and electric vehicle charging stations (EVCS) and remaining energy can be supplied to the grid. In this work, a hybrid system composed of wind and solar is designed and modelled in Simulink (MATLAB) and tested on real data of wind speed and validated by Opal‐RT simulator. From the simulation result, it is estimated that total electrical power output of a single solar‐wind tower is around 15 to 20 kWh in a day under the assumed conditions.

Batteries, particularly lithium‐ion batteries, are sensitive to temperature changes. Battery thermal management systems (BTMS) are essential in various battery‐powered applications, especially electric vehicles (EVs) and portable electronic devices. This study examines the importance of phase change material (PCM) in battery packs using numerical analysis. An examination is conducted on a battery pack consisting of 18 650 battery cells arranged in a 5 × 5 configuration. A comparative analysis is performed to evaluate the thermal efficiency of the battery pack with and without PCM. The study examines the influence of ambient conditions and charging rates on the selection of PCM for battery packs. A hybrid cooling solution utilizing PCM and a water tube has also been investigated against conventional passive PCM‐based BTMS. Additionally, two types of fins, namely circular and spiral fins, are introduced to improve the heat transfer rate. PCM‐based cooling systems are most effective when the ambient temperature is below the melting temperature of the PCM. However, when the ambient temperature exceeds the melting temperature of the PCM, this cooling system outperforms conventional PCM‐based cooling. The maximum temperature is found as 319, 316.9, and 315.3 K using without fin, circular fin and spriral fina, respectively. The spiral fins are found more effective than circular fins under high ambient temperature. In conclusion, The PCM‐with spiral‐fin system demonstrates notable benefits in high‐temperature environments.
